the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is

lowing correction procedures to wash the vehicle:
●Place the electronic key in a location 6 ft. (2 m) or more away from the vehi-

■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle's interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Air intake vent maintenance
●If the vehicle is driven with the air intake vent clogged, the hybrid battery
(traction battery) may overheat and the fuel consumption may increase.
● Depending on the conditions under which the vehicle is used, the air intake
vent may need to be cleaned more regularly.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
■ Cleaning the air intake vent filter
●Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
● If the vehicle is driven with the air intake vent filter clogged, the hybrid bat-

If “MAINTENANCE REQUIRED FOR TRACTION BATTERY COOLING
PARTS SEE OWNER’S MANUAL” is di splayed on the multi-information
display
● It is possible the air intake vent or filter is clogged due to accumulated dust.
Clean the air intake vent and filter, referring to the cleaning method.
● When continuously driven in this state, the hybrid battery (traction battery)
may overheat, which may lead to the driving distance by the electric motor
getting shorter, the fuel consumption worsening, and causing damage.
Clean the air intake vent periodically to prevent dust, etc., from collecting in
the air intake vent or filter.
● If the massage in the multi-information display does not turn off, even if the
air intake vent is cleaned, have the vehicle inspected at your Toyota dealer.
WARNING
■Water in the vehicle
● Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vents, and in the luggage compartment.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 41)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver's view and leading to an accident,
resulting in death or serious injury.
■ When cleaning the hybrid battery (tr action battery) air intake vent/filter
● Do not use water or other liquids to clean the air intake vent/filter. If water
is applied to the hybrid battery (traction battery) or other components, a
malfunction or fire may occur.
● When the air intake vent cover, located below the rear seat cushion on the
left side is to be removed, make sure to turn the power switch off to stop
the hybrid system.
